🔍 Key Concepts

• Pump room hazards on tank vessels (flammable vapors, enclosed space risks) • Difference between intrinsically safe / explosion-proof equipment and normal portable electric tools • Why arcing, sparking, and heat from electric tools are dangerous in a space not certified gas free

💭 Think About

• Which choice is specifically designed and approved to be used where flammable gas or vapor may be present continuously? • For each option, ask: does this tool have any exposed switches, commutators, brushes, or motors that could produce a spark? • Why is the fact that the pump room is not certified gas free critical to deciding which equipment is acceptable?

✅ Before You Answer

• Verify which item is explicitly described as approved for use in hazardous (flammable) atmospheres. • Check which items contain an electric motor or moving parts that normally generate sparks or heat during operation. • Confirm that the selected item is a lighting device only, with no rotating machinery or external wiring that could be damaged and cause a short.
